AI noise cancellation for calls & recordings.

Kleervox sits between your real microphone and your call app. A neural network trained to isolate human speech strips out background noise in real time, and the cleaned audio is exposed as a virtual "Kleervox" microphone that you select in Zoom, Meet, Teams, or any other app.

No. Noise and echo cancellation run entirely on your device — your voice never leaves your computer. Recorded files are cleaned inside your browser, on your computer, too. There is no cloud processing and no one listening; a file is stored only if you choose to save it to your private library.

Any app that lets you choose a microphone: Zoom, Google Meet, Microsoft Teams, Discord, Slack, OBS, and everything else. Kleervox appears as a regular microphone, so there are no plugins or per-app setup.

Yes. Start a 7-day free trial of Pro (or Creator): 7 days free, then $6/month. Cancel anytime. You add a card to start the trial, nothing is charged during it, and we email you a day before the first charge — cancel any time before then and you pay nothing. You can also hear the before-and-after demo on this page, or test it with your own microphone on the browser test page — no account needed. The Free plan is kept for existing members only.

Yes. File Cleanup removes background noise from recorded audio and video files — podcasts, interviews, lectures, MP3, WAV, MP4, MOV and more — right in your browser, without uploading the file for cleaning. It is included in every plan — 2 hours a month on Pro and 25 hours on Creator — and you can try either free for 7 days.

A Windows 10, Windows 11, or Linux computer and any microphone — built-in laptop mics work great. The macOS app is coming soon. Download it, sign in, and you are cleaning calls in under a minute.
